Vertical mill gearboxes require extremely high rated power and
availability. Gearboxes, as one of the key components of vertical
mills, are used for transmitting power, reducing the rotating speed of
the motor to the one required by the mill during operation, and sup-
porting the mill’s grinding table. Higher axial force and partial radial
force generated during the grinding process are transmitted to the
mill foundation through thrust bearing and its housing.
